About Building Words with Affixes
What this skill is
Morphological word building combines base roots with affixes (prefixes at the front, suffixes at the end) to systematically alter word meaning, tense, or part of speech.
When children learn it
Using affixes to determine the meaning of new words begins in 2nd grade and deepens across 3rd through 5th grade morphology (CCSS 2.L.4.b, 3.L.4.b, 4.L.4.b, 5.L.4.b).
Teaching Tips
- Use Lego bricks or index card strips: write prefixes on yellow cards, root words on green cards, and suffixes on blue cards. Snap them together like puzzle trains to build long words.
Common Mistakes
- Accidentally altering the spelling of the base word when adding prefixes.
- Dropping or adding letters incorrectly when attaching suffixes.
- Confusing prefix and suffix positions.
